The Pixies (or just Pixies) are an American alternative rock band formed in 1986 in Boston, Massachusetts. The original lineup comprised Black Francis (lead vocals, rhythm guitar), Joey Santiago (lead guitar), Kim Deal (bass, backing vocals) and David Lovering (drums). The band disbanded acrimoniously in 1993, but reunited in 2004.
Some find pixies to have a human origin or to partake of human nature, in distinction to fairies whose mythology is traced to immaterial and malignant spirit forces. In some discussions pixies are presented as wingless, pygmy-like creatures, however this is probably a later accretion to the mythology.
